Abstract
The Mn3O4/Graphene composites were synthesized by hydrothermal method with the in-situ redox reaction of graphene oxide (GO) and manganese acetate (Mn(Ac)2). The phase structures and morphologies of the materials were characterized by XRD, SEM and TEM. The XPS and IR techniques were used for studying the residual function groups of reduced graphene oxide (RGO). The electrochemical performances of the hybrids were tested in a coin cell. Results showed that the composites prepared with the addition of ammonia water (RM-A) have better performance. The graphenes in RM-A were better-reduced and the Mn3O4 particles were much smaller. The Mn3O4/Graphene composites exhibited a high specific capacity with good rate capability and cycle stability. At the test current density of 0.5 A·g-1, the composites demonstrated a capacity of 850 mAh·g-1, and no capacity decays were observed up to 200 cycles.
